Special Issue Information

Dear Colleagues,

Polymer-based conductive materials are garnering attention as promising candidates for energy storage due to their flexibility, lightweight nature, and tunable electrochemical properties. Conductive polymers, such as polyaniline (PANI) and polypyrrole (PPy), exhibit high electrical conductivity and environmental stability, making them suitable for application in batteries and supercapacitors. Their ability to undergo reversible doping and dedoping processes facilitates efficient charge storage and delivery. Recent advancements in polymer engineering, such as the formation of nanocomposites and their hybridization with other conductive materials, have further enhanced their performance, improving their energy density and cycling stability. Additionally, the processability and low cost of polymer-based materials make them an attractive alternative to conventional metal-based systems. As the demand for flexible and sustainable energy storage solutions grows, polymer-based conductive materials are positioned to play a key role in next-generation energy storage technologies.

Aqueous zinc-ion batteries (ZIBs) represent an emerging energy storage solution that offers significant advantages in terms of safety, cost-effectiveness, and longevity in cycling. Among the various materials available, manganese-based oxides stand out as the most promising options for cathodes due to their impressive theoretical specific capacity, suitable operating voltage, and abundant natural availability. In published reports, pre-embedding is frequently used to modify the layered cathode; however, non-electrochemically active molecular embedding often results in a decrease in battery capacity. In this paper, a hydrothermal method is employed to intercalate poly(o-phenylenediamine) (PoPD) into δ-MnO2 (MO) to produce PoPD-MO cathode materials. Here, PoPD serves a dual role in the cathode: (1) PoPD is inserted into the interlayer of MO, providing support within the intercalation layer, enhancing material stability, increasing ionic storage sites, and creating space for more Zn2+ to be embedded, and (2) inserting PoPD into the interlayer structure of MO effectively expands the space between layers, thus allowing for greater ion storage, which in turn enhances the rate and efficiency of electrochemical reactions. Consequently, PoPD-MO shows remarkable cycling durability and adaptability in ZIBs, achieving a specific capacity of 359 mAh g−1 at a current density of 0.1 A g−1, and even under the strain of a high current density of 3 A g−1, it maintains a respectable capacity of 107 mAh g−1. Based on this, PoPD-MO may emerge as a new cathode material with promising applications in the future. Full article

The advantages of aluminum-ion batteries in the area of power source systems are: inexpensive manufacture, high capacity, and absolute security. However, due to the limitations of cathode materials, the capacity and durability of aluminum-ion batteries ought to be further advanced. Herein, we synthesized a nitrogen-doped tubular carbon material as a potential cathode to achieve advanced aqueous aluminum-ion batteries. Nitrogen-doped tubular carbon materials own an abundant space (367.6 m2 g−1) for electrochemical behavior, with an aperture primarily concentrated around 2.34 nm. They also exhibit a remarkable service lifespan, retaining a specific capacity of 78.4 mAh g−1 at 50 mA g−1 after 300 cycles. Additionally, from 2 to 300 cycles, the material achieves an appreciable reversibility (coulombic efficiency CE: 99.7%) demonstrating its excellent reversibility. The tubular structural material possesses a distinctive hollow architecture that mitigates volumetric expansion during charging and discharging, thereby preventing structural failure. This material offers several advantages, including a straightforward synthesis method, high yield, and ease of mass production, making it highly significant for the research and development of future aluminum-ion batteries.
